Brainstorming

Turn ideas into designs through collaborative dialogue.

Announce: "I'm using the brainstorming skill to explore this feature."

The Flow

EC Search → Branch Setup → Q&A → Approaches → Design → Save

Step 1: Search Memory

Before designing, check what we've done before:

ec_search:
  query: [feature area]
  type: decision

ec_search:
  query: [related patterns]
  type: pattern

ec_search:
  query: [similar features]

Note relevant past decisions that might inform or constrain the design.

Step 2: Branch Setup

Check current state:

git branch --show-current
git status

Load branch convention from config:

ec_search:
  query: project config
  type: config

REQUIRED: Use the AskUserQuestion tool to determine branching:

If on main:

{
  "questions": [{
    "question": "Create a feature branch for this work?",
    "header": "Branch",
    "options": [
      { "label": "Yes", "description": "Create {convention}/<name> branch" },
      { "label": "No", "description": "Stay on main" }
    ],
    "multiSelect": false
  }]
}

If on feature branch:

{
  "questions": [{
    "question": "Where should this new work branch from?",
    "header": "Branch",
    "options": [
      { "label": "Current branch", "description": "Nested feature off current work" },
      { "label": "Main", "description": "Fresh start from main" }
    ],
    "multiSelect": false
  }]
}

This enables branching cycles - features can spawn sub-features.

Step 3: Understand the Idea

REQUIRED: Use the AskUserQuestion tool for all clarifying questions.

• 1-4 questions per tool call
• 2-4 options per question
• Users can always type free text (implicit "Other" option)
• Use multiSelect: true when multiple options can apply

Focus on:

• What problem are we solving?
• What are the constraints?
• What does success look like?

Example:

{
  "questions": [{
    "question": "Who should have access to this feature?",
    "header": "Access",
    "options": [
      { "label": "All users", "description": "Any authenticated user" },
      { "label": "Admins only", "description": "Requires admin role" },
      { "label": "Role-based", "description": "Configurable per role" }
    ],
    "multiSelect": false
  }]
}

Step 4: Explore Approaches

Propose 2-3 approaches with trade-offs. Lead with your recommendation and why.

Search EC for relevant prior decisions:

ec_search:
  query: [technology or pattern being considered]
  type: decision

Keep it conversational:

"I'd go with Option A because [reason]. Option B would work if [condition]. Option C is overkill unless [edge case]."

Step 5: Present Design

Once you understand what we're building, present the design in chunks (200-300 words each). Check after each section if it looks right.

Cover:

• Architecture / component structure
• Data flow
• Key implementation details
• Edge cases / error handling

Be ready to backtrack if something doesn't fit.

Step 6: Save Design

Write to docs/designs/YYYY-MM-DD-<topic>.md

Include:

• Summary of what we're building
• Key decisions and rationale
• Reference to any EC memories consulted
• Placeholder for implementation plan: See: docs/plans/YYYY-MM-DD-<topic>.md

Step 7: Store Decisions

For each significant architectural decision made:

ec_add:
  type: decision
  area: [component]
  content: [What was decided and why]
  rationale: [Trade-offs considered]

Handoff

After saving:

"Design saved to docs/designs/YYYY-MM-DD-<topic>.md. Ready to create the implementation plan?"

If yes → Use @writing-plans (all tasks will follow @tdd red-green-refactor)
